Definitions
- This invention relates to timber preservation and more particularly relates to fungicidal compositons containing aluminum and/or boron and their use in preserving timber.
- the fungicidal compositions of this invention comprise at least one metal-organic compound which contains aluminum and/or boron, at least one divalent metal element or metal radical, the aluminum and/or boron atom and the divalent atom or atoms being linked through oxygen atoms, and at least one carboxylic acid radical, together with a suitable carrier therefor.
- the method according to the invention achieves protection of timber against wood-decaying fungi such as Coniophera epicna.
- the fungicidal compositions may be introduced into the timber by any of the well known processes which ensure that the fungicide is uniformly distributed throughout the timber.
- the fungicidal compositions are preferably uniformly distributed throughout the timber by means of vacuum impregnation, and sawn timber is particularly advantageously preserved by the method according to the invention.
- the carboxylic acid radicals are preferably derived from carboxylic acids containing eight to ten carbon atoms. It has been found that the neodecanoic acid (Versatic 10) radical is particularly suitable on account of its good solubility and ease of processing.
- a particularly preferred compound for use in the method according to the invention is zinc boron versatate.
- Suitable carriers in which the metal-organic compounds are dissolved are organic solvents, preferably hydrocarbons and more preferably white spirit.
- Previously proposed fungicidal compositions have usually contained not less than about 2 to 3% by weight based on the total weight of composition of divalent metal to ensure adequate protection of timber in all environmental conditions over a long period of time.
- Employing the compositions of the present invention much less metal is required to give adequate protection. This is particularly important for timber which is exposed to heavy rainfall since metal soaps may slowly leach through wet timber.
- fungicidal effect of the compounds used in the method according to the invention can be further enhanced by incorporating one or more substituted phenols of known fungicidal activity, for example, o-phenylphenol, nonylphenol and chlorinated phenols.
- the invention provides a fungicidal composition
- a fungicidal composition comprising at least one metal-organic compound which contains aluminum and/or boron, at least oe divalent metal element or metal radical, the aluminum and/or boron atom and the divalent atom or atoms being linked through oxygen atoms, and at least one carboxylic acid radical, and one or more substituted phenols together with a suitable carrier therefor.
- compositions of the present invention will be further illustrated by reference to a series of tests comparing the fungicidal properties of compositions of the present invention with a known commerically available fungicide used for treating timber.
- compositions which comprised zinc boron versatate or zinc naphthenate (comparison) dissovled in white spirit in different concentrations were subjected to a series of tests, described below, using blocks of Scots pine (Pinus Sylvestris) sapwood which were subjected to infestation by the wood destroying fungus Coniophera putenana.
- Wood blocks sized 14.5 ⁇ 10 ⁇ 7 mm were oven dried for 18 hours, cooled and weighed. They were then transferred to a glass vessel which was evacuated of air down to a pressure of less than 10 mm. of mercury and were then held at this pressure for 10 minutes. The fungicidal treating solution was then admitted to the vessel to cover the blocks which were left covered for two hours to ensure full and uniform impregnation. The blocks were removed from the solution, allowed to drain and then reweighed to determine the uptake of the fungicidal treating compound. The blocks were then allowed to dry slowly for three weeks and then were sterilized by exposure to 1,2-expoxypropane vapor followed by ventilation in sterile air.
- the blocks were then transferred aseptically to actively growing soil feeder block cultures of Coniophera tenua and incubated for six weeks at 22° C. At the end of this period the extent of overgrowth on the test blocks was noted. The blocks were removed from the culture, oven dried and reweighed so that the loss in mass of each block due to fungal decay could be noted.
- Wood blocks sized 14.5 ⁇ 10 ⁇ 7 mm, were impregnated with fungicidal compositions as described in Example 1 and allowed to dry slowly for three weeks. The blocks were then leached in deionized water according to the following procedure:
- the treated wood blocks were vacuum impregnated with water and allowed to soak for two hours. The water was then poured away and a further 30 ml. was added. The water was changed after 24 hours and 48 hours and thereafter at a minimum interval of 24 hours and a maximum of 72 hours until the water had been changed on a total of 10 occasions.
- the blocks were then placed in a well ventilated oven at 45° to 50° C. in order to dry to a moisture content of about 20% by weight.
- the blocks were then sterilized and exposed to cultures of Coniophera tenua as described in Example 1.
- the leaching process did in most cases cause some redution in fungicidal activity, but the retained activity of the fungicidal compositions of the present invention was never inferior and in certain cases was superior to the corresponding comparative metal naphthenate compositions.
- the blocks were allowed to dry slowly for three weeks, after which four of each set of six were sterilized with 1,2-epoxypropane vapor for 24 hours and then ventilated in sterile air for 72 hours.
- the blocks were then transferred aseptically to actively growing soil feeder block cultures of Coniophera tenua and incubated for six weeks at 22° C. After this period the culture vessels were examined and the extent of overgrowth on the test blocks noted.
- the blocks were removed from culture, any adhering mycelium scraped off and the blocks weighed, oven dried and reweighed so that the loss in weight of each block due to fungal decay could be calculated. The following results were obtained:
